If you’re a woman living with Type 1 diabetes and you’ve noticed that your insulin needs feel different than they used to—even though your food and routines haven’t changed—I want you to hear this first:
You’re not imagining it.
And you’re not doing anything wrong.
This is something I noticed in my own body as I got closer to 40. My insulin sensitivity shifted. Blood sugars felt less predictable. Corrections worked differently. Basal needs changed.
And yet…
I was eating the same way.
My routines were steady.
My effort hadn’t dropped.
For a long time, women with Type 1 diabetes haven’t been given good explanations for why this happens. But the more I’ve learned—and the more women I’ve worked with—the clearer it’s become:
Hormonal shifts start earlier than most of us are told, and they directly affect how our bodies respond to insulin.
Hormones Start Shifting Earlier Than You Think
Perimenopause education is still relatively new, but it’s something I’ve been deep in for the last several years—because it explains so much of what women with Type 1 diabetes start noticing in their mid-to-late 30s.
Hormones don’t suddenly change at menopause.
Estrogen, progesterone, and cortisol can begin shifting as early as age 35. And those shifts influence things like:
- Insulin sensitivity
- Glucose variability
- Stress response
- Sleep quality
- Inflammation
Which means you can be doing the exact same things you’ve always done and suddenly get very different results.
That’s often the moment women start questioning themselves.
But this isn’t about willpower or discipline.
It’s about biology.
Why Type 1 Diabetes for Women Can Feel Like a Moving Target
I keep coming back to this analogy because it resonates so deeply with the women I work with.
Living with Type 1 diabetes as a woman is a lot like playing Mahjong.
Every year, there’s a new card.
The game is the same—but the combinations change.
What worked before doesn’t automatically work now.
The goal isn’t to play harder or second-guess yourself.
The goal is to recognize when you’re holding a new card—and adapt.
And that adaptation doesn’t come from restriction or forcing your body into submission. It comes from understanding how your body is responding in this season of life.
A Real Example from a recent T1D Functional Nutrition Client: C.D.’s Story
C.D. came to coaching with goals I hear from so many women with Type 1 diabetes:
She wanted sustainable weight loss.
Better digestion (especially long-standing constipation).
Improved insulin sensitivity.
And progress without extremes or quick fixes.
What stood out immediately wasn’t a lack of effort. She had been showing up for her health for years.
What was missing wasn’t motivation or consistency—it was clarity.
Looking Beyond Food and Numbers
Instead of jumping straight into another plan or protocol, we slowed things down and looked at the bigger picture.
What systems in her body needed support right now?
One of the biggest missing links turned out to be her gut.
Digestive challenges and slow motility had been part of C.D.’s story for as long as she could remember, but no one had ever connected how much that was influencing her blood sugars, insulin needs, and overall progress.
Gut health plays a meaningful role in:
- Insulin sensitivity
- Inflammation
- Hormone metabolism
- Blood sugar predictability
When digestion is sluggish and the microbiome is out of balance, blood sugars can feel harder to manage.
Adapting Instead of Forcing
Rather than chasing the next solution or pushing harder, we took a thoughtful, experimental approach.
We used information—not pressure—to guide decisions.
That shift alone can feel incredibly relieving for women who have spent years feeling like they need to “figure it out” on their own.
As C.D. shared:
“I’ve gained so much more understanding of what systems in my body need more support and what tools I can experiment with to move things in a different direction. Discovering new ways to approach health provides hope—and hope is everything when dealing with health challenges.”
That’s what adapting looks like.
Not fixing yourself.
Not starting over.
Just learning how to support your body as it changes.
You’re Not Broken—You’re in a New Season
If your insulin needs feel different than they used to—and no one ever explained why—you’re not alone.
For women with Type 1 diabetes, hormones, gut health, stress, and sleep all interact with insulin sensitivity in ways traditional diabetes education often overlooks.
The work isn’t about perfection.
It’s about awareness, support, and adaptation.
And when those pieces come together, things start to make sense again.
If your body feels different than it used to, you’re not broken.
You’re just playing a new card.
